To a whom, it TVI/(J/Z/ concern.-

Be it known that I, THEODORE HIRAM PROSKIG, a citizen of the United States, and a resident of Denver, in the county of Denver and State of Colorado, have invented a new and Improved Car, of which the following is a full, clear, and exact description.

The invention relates to the removal of material loosened by blasting operations carried on in mines, tunnels, and like work; and its object is to provide a new and improved car more especially designed for directly receiving the material resulting from the blasting operations and for allowing quick and convenient removal of the material from the breast of the mine or tunnel and to permit dumping of the material outside of the tunnel or mine from either end or side of the car.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement in position in a mine or tunnel. Fig. 2 is an end elevation of the same. Fig. 3 is a cross-section of the car-body substantially on the line 3 3 in Fig. 1, and Fig. 4 is an enlarged longitudinal section of one of the pneumatic cushioning devices for the carbody. l

The truck A of the car is mounted to travel on track-rails B, set on the bottom of the mine or tunnel O to permit of conveniently running the car in or out of the mine or tunnel. On the top of the car-truck A is held a suitable king-bolt D, on which is mounted to turn a platform E, a suitable ball-bearing E being preferably interposed between the platform and the top of the car-truck A. The platform E is removably connected at one side by a pivot F with the under side of the car-body G, preferably made of suitable sheet metal in the form of a trough that is, open at the ends and having curved sides, as plainly indicated in the drawings. This car body Gis reinforced at the outside by longitudinallyeXtending ribs G and transversely-extending ribs G so as to render the-car-body exceedingly strong and durable. The forward end of the car-body G is provided with a relatively immovable extension G, arranged at an angle to the car-body, so that when the latter is swung into an inclined or active position, as illustrated in Fig. 1, then the extension G is approximately in a horizontal position and close to the bottom of the shaft or mine in which the blasting operations are carried on.

The rear end of the car-body G is connected by one, two, or more ball-and-socketjoints H with a corresponding number of cylinders I, connected adjacent to the ball and socket joints with a hose J, leading to asuitable source of compressed-air supply under the control of an operator. In each of the cylinders I is mounted to slide a piston K, having its pistonrod K extending through the outer end of the cylinder 1, and the outer terminal of the piston-rod K is preferably pointed to allow of conveniently anchoring or engaging the pointed end with the side or other part of the tunnel or mine C to support the car-body G in an inclined position, as indicated in Figs. 1 and 2.

When the car is moved up close to the breast in the mine or tunnel and the car-body is rocked into an inclined position, as shown, and the blasting is taking place by successively firing the several shots in the usual manner, then the greater part of the material loosened by the blasting operation falls onto the inclined car-body G, thus loading the same, the shock of the blasting operation being readily taken up by the car-body, asthe latter is pnoumat' ically cushioned by the air in the cylinders I and pressing on v the pistons K. After the blasting operation is completed the operator releases the pneumatic pressure in the cylinders I, so that the car-body G, by its own weight and that of the load, readily swings back into a horizontal position. The loosened material which may have fallen alongside the car can be readily shoveled onto the car-body G, and then the car is run out of the mine or tunnel to be dumped on either end or side, as the platform E permits turning the car-body G into any desired direction, and then the carbody G can be swunginto an inclined position to allow the material to slide off the car-body.-

If desired, the truck A can be disconnected from the car-body G at the time the latter is arranged in an inclined active position by the operator simply withdrawing the pivot F and running the car-truck A out of the mine or tunnel along the track-rails B. In a like mannet after the blasting operation is completed the car-truck A can be run back and again ITO connected with the car-body G previous to releasing the pneumatic pressure in the cylinders I.

It is understood that sufficient room must be left on both sides of the car for the escape of the miners after the shots are ready to be fired, and hence it is necessary to load the material which may fall to the sides of the car into the body after the shots have been fired.

From the foregoing it will be seen that by the arrangement described the loosened material can be quickly removed from the mine or tunnel and dumped outside of the mine or tunme] to either side or end of the car. By removing the loosened material quickly from the mineor tunnel the miners can return immediately to work, with a view to prepare new shots for the next blasting operation.

As the gases incident to the firing of the shots settle very quickly among the loosened material and as the latter is quickly carried away, it is evident that the mine or tunnel is kept comparatively pure for the immediate return of the miners to work.

Having thus described my invention. 1 claim as new and desire to secure by Letters Patent 1. A car for receiving the material resulting from a blasting operation, comprising means for cushioning the body thereof during the fall of the material thereonto, embodying a device for anchoring the car in an inclined position.

2. A car for receiving the material resulting from a blasting operation, comprising pneumatic means for cushioning the body thereof during the fall of the material thereonto, embodying a device for anchoring the car in an inclined position.

3. A car for receiving the material resulting from a blasting operation, comprising a body adapted to be carried to an inclined position, and means for cushioning the body in such position during the fall of the material thereonto, embodying an anchoring device for the car.

4:. A car for receiving the material resulting from a blasting operation, comprising a body, a supporting-truck for the body having detachable relation thereto, said body being adapted to be carried to an inclined position, and means for cushioning the body in said position during the fall of the material thereonto, embodying an anchoring device for the car.

5.
